Transfers and land demand for housing: Evidence from a municipality in northwestern México

Nicolás Guadalupe Zúñiga Espinoza (2021, [Artículo, Artículo])

Objective: to analyze the destination of conditional transfers (TC) to finance public services on land managed for housing in a municipality in the Northwest of Mexico. Methodology: based on semi-structured interviews, analysis of documents and data consulted in Inegi, Coneval, Inafed, Municipal Governments of Guasave and State of Sinaloa, it was possible to develop this work for the period 2013 to June 2020. Results: the evidence indicates that of the 6.9-hectare surface managed for housing, 50 % of the lots are vacant and in only a part of them there are houses or unfinished constructions (17 %). It is more about an interest in fattening land and taking advantage of financing, with transfers, to introduce free public services such as electricity, water and drainage.

Casos de estudio en México en el sector de la construcción

Aurora Poó Rubio (2010, [Artículo])

El planeamiento del estudio de casos múltiples para estudiar las empresas en el sector de la construcción permitió a la presente investigación el examen del comportamiento de varias empresas. Aunque estas no eran completamente similares, su comparación pudo ser llevada a cabo, identificando prácticas exitosas, así como aquellas que derivaron en grandes problemas para las organizaciones. Referente a la evaluación, las empresas no necesariamente cumplieron completamente con todas las premisas planteadas en sus hipótesis de trabajo. Se observó que las organizaciones estudiadas tuvieron un comportamiento diferenciado. SIDEK, tuvo aciertos espectaculares, pero igual de impactante fueron sus contratiempos. Se desempeñó hasta el 94 como una gran empresa, pero en la segunda mitad de los 90's produjo resultados contrastantes. ARA respondió satisfactoriamente a todas las evaluaciones aplicadas y su desempeño ha continuado siendo exitoso, basado en políticas de trabajo y financieras visionarias pero conservadoras al mismo tiempo, lo que pone en manifiesto las experiencias vividas en los años de crisis económica del país. ICA fue sumamente exitosa durante un importante período de tiempo y sufrió fuertes afectaciones por los cambios contextuales, anotados en el estudio correspondiente; identifica tanto áreas disfuncionales como momentos en el tiempo de fragilidad empresarial; actualmente con la generación de obra pública y el Programa Nacional de Infraestructura, su desempeño ha vuelto a ser exitoso y se mantiene como la constructora número 1 del país. En nuestro país son pocos los Casos de Estudio de empresas mexicanas y no se localizó ninguna información respecto a firmas del sector de la construcción. Lo anterior muestra que hay un gran camino que recorrer en cuanto al estudio de las firmas por estos medios y que el diagnóstico que se puede elaborar de su desempeño es fundamental para el diseño de la Planeación Estratégica de las empresas del sector de la construcción en México.

Weed management and tillage effect on rainfed maize production in three agro-ecologies in Mexico

Simon Fonteyne Abel Jaime Leal González Rausel Ovando Ravi Gopal Singh Nele Verhulst (2022, [Artículo])

Maize (Zea mays L.) is grown in a wide range of agro-ecological environments and production systems across Mexico. Weeds are a major constraint on maize grain yield, but knowledge regarding the best weed management methods is lacking. In many production systems, reducing tillage could lessen land degradation and production costs, but changes in tillage might require changes in weed management. This study evaluated weed dynamics and rainfed maize yield under five weed management treatments (pre-emergence herbicide, post-emergence herbicide, pre-emergence + post-emergence herbicide, manual weed control, and no control) and three tillage methods (conventional, minimum and zero tillage) in three agro-ecologically distinct regions of the state of Oaxaca, Mexico, in 2016 and 2017. In the temperate Mixteca region, weeds reduced maize grain yields by as much as 92% and the long-growing season required post-emergence weed control, which gave significantly higher yields. In the hot, humid Papaloapan region, weeds reduced maize yields up to 63% and pre-emergence weed control resulted in significantly higher yields than treatments with post-emergence control only. In the semi-arid Valles Centrales region, weeds reduced maize yields by as much as 65%, but weed management was not always effective in increasing maize yield or net profitability. The most effective weed management treatments tended to be similar for the three tillage systems at each site, although weed pressure and the potential yield reduction by weeds tended to be higher under zero tillage than minimum or conventional tillage. No single best option for weed management was found across sites or tillage systems. More research, in which non-chemical methods should not be overlooked, is thus needed to determine the most effective weed management methods for the diverse maize production systems across Mexico.

Review of Nationally Determined Contributions (NCD) of China from the perspective of food systems

Tek Sapkota (2023, [Documento de trabajo])

China is the largest emitter of greenhouse gases (GHG) and one of the countries most affected by climate change. China's food systems are a major contributor to climate change: in 2018, China's food systems emitted 1.09 billion tons of carbondioxide equivalent (CO2eq) GHGs, accounting for 8.2% of total national GHG emissions and 2% of global emissions. According to the Third National Communication (TNC) Report, in 2010, GHG emissions from energy, industrial processes, agriculture, and waste accounted for 78.6%, 12.3%, 7.9%, and 1.2% of total emissions, respectively, (excluding emissions from land use, land-use change and forestry (LULUCF). Total GHG emissions from the waste sector in 2010 were 132 Mt CO2 eq, with municipal solid waste landfills accounting for 56 Mt. The average temperature in China has risen by 1.1°C over the last century (1908–2007), while nationally averaged precipitation amounts have increased significantly over the last 50 years. The sea level and sea surface temperature have risen by 90 mm and 0.9°C respectively in the last 30 years. A regional climate model predicted an annual mean temperature increase of 1.3–2.1°C by 2020 (2.3–3.3°C by 2050), while another model predicted a 1–1.6°C temperature increase and a 3.3–3.7 percent increase in precipitation between 2011 and 2020, depending on the emissions scenario. By 2030, sea level rise along coastal areas could be 0.01–0.16 meters, increasing the likelihood of flooding and intensified storm surges and causing the degradation of wetlands, mangroves, and coral reefs. Addressing climate change is a common human cause, and China places a high value on combating climate change. Climate change has been incorporated into national economic and social development plans, with equal emphasis on mitigation and adaptation to climate change, including an updated Nationally Determined Contribution (NDC) in 2021. The following overarching targets are included in China's updated NDC: • Peaking carbon dioxide emissions “before 2030” and achieving carbon neutrality before 2060. • Lowering carbon intensity by “over 65%” by 2030 from the 2005 level. • Increasing forest stock volume by around 6 billion cubic meters in 2030 from the 2005 level. The targets have come from several commitments made at various events, while China has explained very well the process adopted to produce its third national communication report. An examination of China's NDC reveals that it has failed to establish quantifiable and measurable targets in the agricultural sectors. According to the analysis of the breakdown of food systems and their inclusion in the NDC, the majority of food system activities are poorly mentioned. China's interventions or ambitions in this sector have received very little attention. The adaptation component is mentioned in the NDC, but is not found to be sector-specific or comprehensive. A few studies have rated the Chinese NDC as insufficient, one of the reasons being its failure to list the breakdown of each sector's clear pathway to achieving its goals. China's NDC lacks quantified data on food system sub-sectors. Climate Action Trackers' "Insufficient" rating indicates that China's domestic target for 2030 requires significant improvements to be consistent with the Paris Agreement's target of 1.5°C temperature limit. Some efforts are being made: for example, scientists from the Institute of Environment and Sustainable Development in Agriculture, Chinese Academy of Agricultural Sciences (IEDA-CAAS) have developed methods for calculating GHG emissions from livestock and poultry farmers that have been published as an industrial standard by the Ministry of Agriculture and Rural Affairs, PRC (Prof Hongmin Dong, personal communication) but this still needs to be consolidated and linked to China’s NDC. The updated Nationally Determined Contributions fall short of quantifiable targets in agriculture and food systems as a whole, necessitating clear pathways. China's NDC is found to be heavily focused on a few sectors, including energy, transportation, and urban-rural development. The agricultural sectors' and food systems' targets are vague, and China's agrifood system has a large carbon footprint. As a result, China should focus on managing the food system (production, processing, transportation, and food waste management) to reduce carbon emissions. Furthermore, China should take additional measures to make its climate actions more comprehensive, quantifiable, and measurable, such as setting ambitious and clear targets for the agriculture sector, including activity-specific GHG-reduction pathways; prioritizing food waste and loss reduction and management; promoting sustainable livestock production and low carbon diets; reducing chemical pollution; minimizing the use of fossil fuel in the agri-system and focusing on developing green jobs, technological advancement and promoting climate-smart agriculture; promoting indigenous practices and locally led adaptation; restoring degraded agricultural soils and enhancing cooperation and private partnership. China should also prepare detailed NDC implementation plans including actions and the GHG reduction from conditional targets.
